Abstract
The present invention generally relates to deuterium-enriched hyaluronan, d-HA, compositions containing the same, methods of using the same, and methods for making the same.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. A topical anti-wrinkle and anti-aging moisturizing composition, comprising: a d-HA of the formula:
or a cosmetically acceptable salt thereof, wherein:
the d-HA has a molecular weight selected from about 15 kDa to about 10 MDa; and,
each R D and R D1 is independently hydrogen or deuterium, provided that at least 1% of the total number of R D and R D1 groups present are D;
and a cosmetically acceptable excipient;
wherein the composition is in the form, selected from: a cream, ointment, gel, serum, hydrogel patch, and liposome preparation.
2. The composition of claim 1 , wherein the d-HA is of formula d-HA1:
or a pharmaceutically acceptable salt thereof;
wherein:
each R D1 is independently hydrogen or deuterium, provided that at least 1% of the R D1 groups present are D.
3. The composition of claim 1 , wherein the d-HA is of formula d-HA B1 :
or a pharmaceutically acceptable salt thereof;
wherein:
each R D1 is independently hydrogen or deuterium, provided that at least 1% of the R D1 groups present are D.
4. The composition of claim 1 , wherein the d-HA is of formula F:
or a pharmaceutically acceptable salt thereof.
5. The composition of claim 1 , wherein the d-HA is of formula d-HA 2 :
or a pharmaceutically acceptable salt thereof;
wherein:
each R D is independently hydrogen or deuterium, provided that at least 1% of the R D groups present are D.
6. The composition of claim 1 , wherein the molecular weight of the d-HA is selected from about 0.1 MDa to about 5 MDa.
7. The composition of claim 1 , wherein the molecular weight of the d-HA is selected from about 0.5 MDa to about 3 MDa.
8. The composition of claim 1 , wherein the molecular weight of the d-HA is about 1-2.5 MDa.
9. The composition of claim 1 , wherein the molecular weight of the d-HA is selected from about 15 kDa to about 100 kDa.
10. The composition of claim 1 , wherein the molecular weight of the d-HA is selected from about 15 kDa to about 35 kDa.
11. The composition of claim 1 , wherein at least 5% of the total number of R D and/or R D1 groups present are D.
12. The composition of claim 1 , wherein at least 10% of the total number of R D and/or R D1 groups present are D.
13. The composition of claim 1 , wherein at least 20% of the total number of R D and/or R D1 groups present are D.
14. The composition of claim 1 , wherein at least 30% of the total number of R D and/or R D1 groups present are D.
15. The composition of claim 1 , wherein at least 40% of the total number of R D and/or R D1 groups present are D.
16. The composition of claim 1 , wherein at least 50% of the total number of R D and/or R D1 groups present are D.
17. The composition of claim 1 , wherein at least 60% of the total number of R D and/or R D1 groups present are D.
18. The composition of claim 1 , wherein at least 70% of the total number of R D and/or R D1 groups present are D.
19. The composition of claim 1 , wherein at least 80% of the total number of R D and/or R D1 groups present are D.
20. The composition of claim 1 , wherein at least 90% of the total number of R D and/or R D1 groups present are D.
21. The composition of claim 1 , wherein the composition is in the form of a hydrogel patch.
22. The composition of claim 21 , wherein the hydrogel patch is suitable for iontophoretic delivery of the d-HA into the skin.
23. The composition of claim 1 , wherein the composition is in the form of a liposomal preparation.
24. The composition of claim 23 , further comprising: skin-penetrating peptides for delivery of the d-HA into the skin.
25. The composition of claim 1 , wherein the cosmetically acceptable excipient is a cosmetically acceptable peptide or transdermal delivery facilitating agent.Cited by (0)
